Hi,
I opened up mu G2 to clean dust out and noticed something a bit strange.
There appears to be a wire link connected U26 (pin 14) to R26, but on my G2 the wire link is not soldered on any more at one end, it 'floating' next to it.

I opened my G2 Keyboard (but not my G2X) and I don’t see any evidence of that jumper wire on my main board. I did a quick check and found that the other end of R26 is connected to the logic Vcc power supply rail which is also connected to pin 14 of U26 (point A in your picture). That jumper would have shorted whatever is connected to R26 at point B directly to the Vcc rail instead of normally going through that 10k resistor. Unless other G2 owners chime in that there are connected jumpers on their boards, I would not recommend reconnecting it. In fact, it is a bit dangerous to leave that jumper floating like that where it could accidentally short some other part of the circuit to the Vcc rail. I would remove the jumper entirely or at least insulate the floating end.

Looks like someone did an experiment there, yup .. but without a schematic (and likely source code would be needed too) it is hard to tell what the idea was ... to me it looks like a previous owner did it, the soldering is not factory quality (not that it is bad soldering)._________________Jan

Hi,
thanks for all the feedback, Im not the original owner but i have seen another couple of thinks soldered on.
To make it even more of a mystery, someone posted me this pic, of another G2 and you can see the link is there too!
